EZboil for Step Mashing and Boiling Process Automation, DSPR310D
Version 1.1 (Aug, 2018)
Caution
•
This controller is intended to control equipment under normal operating
conditions. Failure or malfunction of the controller may lead to abnormal
operating conditions, which result in personal injury or damage to the
equipment or other property. Devices (limit or safety controls) or systems
(alarm or supervisory) intended to warn of or protect against failure or
malfunction of the controller must be incorporated into and maintained as part
of the control system.
•
Installing the rubber gasket supplied will protect the controller front panel from
dust and water splash (IP54 rating). Additional protection is needed for higher
IP rating.
•
This controller carries a 90-day warranty. This warranty is limited to the
controller only.

Figure 1. The front panel of DSPR310D.
1). Top display.
This display indicates the temperature sensor readout value. it
may also show time and temperature alternately. (see section 4)
2). Bottom display.
In boiling mode, this display will show the percentage of
power being sent to the external SSR after the initial heat up phase. In mashing
mode, this display will show the set temperature. It may also flash step number
alternately under these two modes. (see section 4)
3). Temperature setting adjusting indicator.
This is the small dot at the lower
right corner. In mashing mode, when temperature set point is adjusted, it will
start to flash. It reminds you that you need to press the knob to confirm the
change. Otherwise, the temperature setting will return back in 2 seconds after
you stop the adjustment.
4). AL1 indicator
. This red LED indicates the status of Relay 1 (AL1). When it
is on, relay 1 is closed; when it is off, relay 1 is open.
5). AL2 indicator
. This red LED indicates the status of Relay 2 (AL2). When it
is on, relay 2 is closed; when it is off, relay 2 is open.
6). Mashing mode indicator (MASH).
This yellow LED light indicates the
operation mode of the controller. When it is on, controller is in mashing mode;
when it is off, controller is in boiling mode.
7). Output indicator (OUT).
This green LED light is SSR output indicator. It
shows how much power the regulator is sending out (as a 12VDC control signal
pulse through terminal 6 and 7). When it is solid ON, the output is 100% on.
When it is off, there is no output. When it is flashing, the frequency of the flashing
is an indication of high or low power output. Higher frequency means higher
power output percentage.
8). Rotary switch (knob).
Turn it clockwise to increase the output power (or
selected parameter value); turn it counter-clockwise to reduce the output power
(or selected parameter value). Press it momentarily to reset the timer (if enabled)
and to switch between mashing and boiling mode. Press and hold it for 5
seconds to enter parameter settings menu. (see section 6)
9). Program Function Key A & B.
There are two function k
eys named “A”
(or
“RUN”) and “B”
(or “HOLD/STOP”)
. Key A can be used to start or resume the
program (step mashing mode) or power output/timer (boiling mode). Key B can
be used to hold or stop the program or timer. Please see section 5.2.2 and 5.3.3.
Key A can also be used to mute the built-in buzzer in specific situations. Please
refer to section 5.3.3 for more details.

Figure 2. Terminal assignments of DSPR310D.
3.1 Sensor connection
DSPR310D only accepts Pt100 RTD temperature sensor. For a three-wire RTD
with standard DIN color code, the two red wires should be connected to the
terminals 3 and 4. The white wire should be connected to terminal 5. For a two-
wire RTD, the wires should be connected to terminals 4 and 5. Jump a wire
between terminals 3 and 4.
3.2 Power to the controller
The power cables should be connected to terminals 9 and 10. Polarity does not
matter. It can be powered by 85-260 VAC power source. Neither a transformer
nor jumper is needed to wire it up. For the consistent with the wiring example
